    Coupler should be here tomorrow. Maybe after that I can crack it open and see what the problem is.

    a bad PCV valve will make a terrible grinding noise coming from the blower area. run the engine and take off the oil cap and see if it stops. i had that issue on my car and i didnt find out till after swapping the tensioner, blower and water pump

    You don't. You just live with it from what I have heard.

    I did this and I wish it had worked but no joy. I spent some more time listening and looking around. I don't think it is the supercharger. I think think it is lower down. I am afraid it is rod knock or something like that.

    Well it isn't a rod knocking but almost as bad. I have a cracked flexplate. I guess the end of this thread is that not all rock in a tumbler noises are from the supercharger coupler. I kinda wish that had been the problem. Anyway thanks to everyone who posted and tried to help out.
